Hi, I have a i5 2500k with a hyper 212 evo, a Asus P8P67, a Sapphire HD 7950, a Enthoo Pro M Acrylic with both stock fans, a WD Blue HDD and a EVGA 750W PSU. I want to know how I can make my PC quieter. There are quite a bit of fans in it so that is why there is some noise going on as well as my hard drive spinning which causes some noise as well. What are some things I can do to remove sound?
